Problem

Slow Framerates with nVidia dual monitor setup

Causes and Solutions

Cause 1 - older nVidia Dual Monitor settings

When using two monitors, the graphics driver attempts to use 3D acceleration for both monitors. The result is that the GPU is required to split its resources across two monitors.

Solution #1: Go into the NVidia Control Panel and set the option "Mult-Disply/Mixed GPU Acceleration" to "Single-Display-Performance-Mode".
